I have a K&N air intake on my 05 v6 and at 2000 rpm it whistles really loud I was wondering if this is normal. I have checked and all the connections are nice and tight.

 

It's normal. Mine doesn't whistle though. It's more of an annoying suction sound.

 

Mine doesn't whistle, either. But I do love the suction sound!

 

mine whistles too once I get to a certain rpm or something. But yeah, mostly the suction sound, and it is really annyoing when you're trying to have a conversation with someone...But it just looks so damn awesome. lol.

 

its normal but once you get a bigger throttle body it will stop. It did that with me. Now it sounds like this whenever i press the gas.

but not that loud

 

Well, that doesn't apply to me because my exhaust is loud as hell, haha. The suction is only a whisper.

 

mine sucks and whistles..
